From: A robust anisotropic diffusion filter with low arithmetic complexity for images
Anisotropic smoothing of lamp image for n = 25. a Original image, b PM (λ = 0.25), and c FORADF (λ = 1). λ represents the control parameter, and n represents the number of iterations. The results are given to demonstrate the superiority in anisotropic behavior of the proposed FORADF in comparison with the benchmark Perona-Malik anisotropic diffusion filter
